摘要： A chemical vapor sensor is provided that passively measures a chemical species of interest with high sensitivity and chemical specificity. In an aspect, ethanol vapor in a vehicle cabin is measured, and sufficient sensitivity is provided to passively detect a motor vehicle driver that exceeds a legal limit of blood alcohol concentration (BAC), for use with vehicle safety systems. The sensor can be situated in an inconspicuous vehicle cabin location and operate independently without requiring active involvement by a driver. A vapor concentrator is utilized to amplify a sampled vapor concentration to a detectible level for use with an infrared (IR) detector. In an aspect, in comparison to conventional chemical sensors, the sensitivity of detection of ethanol vapor is increased by a factor of about 1,000. Further, a single channel of infrared detection is utilized avoiding spurious infrared absorption and making the chemical vapor sensor less costly to implement.

摘要： A method and apparatus for protecting an optical transmission measurement when sensing transparent materials. Sensing apparatus located in a housing directs a light beam at an upward angle to a sheet of transparent material and detects downward surface reflections of the beam from the transparent material. The light beam and the reflections pass through a transparent protective layer on the housing. A flow of clean air is passed between the protective layer and the transparent material to remove particles and liquid from the protective layer and from the space between the protective layer and the transparent material. Preferably, the protective layer is either made from a hydrophobic material or has a hydrophobic surface coating to facilitate blowing liquid and particles from the surface.
